Please go ahead.

You (and however many monkeys) go and do that (oh, and BTW, the
licensing model is not actually irrelevant here -- as you come to
realize how complex actually doing that is, and the money you could
make doing a non-OSS-licensed version of something extremely distant
from that but still actually useful to the otherwise mostly clueless
(aka "the great unwashed") computer users... Oh, sorry, I forgot you
were idealizing at a totally reality-divorced level!!! Just ignore a
grizzled old fart like me who knows how shite actually works...).
